NinJitSu

I am not sure, no offence for those who practice the art, but lets face it, its not something you can use everyday, I mean what if someone attacks you with a knife or some **** like that, what are you gonna do, dance around and crawl through the shadows, thats just Martial Art Bullshit, again no offence, but all due respect this is a type of art where its not used on the streets, its just not pratical, any thoughts ?

I mean I owe NinJitSu allot of respect, but its just not the right tactics for defending youreself in the streets, what if a Ninja lady was getting raped, what is she going to do ? cut the guys head off, or throw those little stars in his face?
